Abstract: 754,258. Switches held set and freed mechanically; fluid actuation of switches. UNI-TUBO SOC. ANON. April 15, 1954, No. 11166/54. Class 38(5) [Also in Group V] The movable member 36<SP>1</SP> of a contact switch 36 is normally held out of contact by a spring S<SP>1</SP> but is moved to the closed position shown by clockwise movement of a cam 33 and is held closed by a pawl 40 engaging ratchet teeth 48 on a disc 30 that carries the cam. The disc is rotatable about a shaft 31 and is fixed to a rod 28. When a fluid-pressure reciprocated piston 22 descends, a projection 27 thereon rocks the rod to the broken-line position and hence closes the switch. When the piston rises, it does not disturb the pawl. When the piston descends again it releases the pawl by rocking an arm 38 pivoted on a shaft 37, this rocking movement raising the pawl arm 39 by way of a pin 43. On this second descent of the piston the projection 27 may not reach the rod 28 (see Group V) so that the switch remains open until the piston descends to a predetermined low position.

Title: Improvements in or relating to hydraulic shock absorbers
IPC: F16F9/48
Filed: 1943-07-13
Abstract: 575,415. Hydraulic shock-absorbers. MONROE AUTO EQUIPMENT CO. July 13, 1943, No. 11388. Convention date, July 20, 1942. [Class 108 (iii)] In a hydraulic piston- and - cylinder shockabsorber means are provided for maintaining fluid in sealing relation to a port 15 in the cylinder 11 which permits escape of fluid to a reserve chamber 13 as the piston 25 moves towards the port, valvecontrolled ports 30 in the piston permitting retarded continued movement of the piston in the same direction after the piston passes the port 15. The port sealing means which prevents the passage of air through the port 15 comprises a sleeve 46 surrounding and secured to the upper end of the cylinder 11 by a head 16 and engaged with the lower end of the cylinder at circumferentiallyspaced points 48. The head 16 closes the upper end of the cylinder and is secured by a ring 21 screwed into the outer tube 12, the ring clamping a seal 22 in position and also preventing the tube 12 from moving upwardly relatively to the cylinder 11. To prevent fluid in the cylinder escaping along the piston-rod 24, a seal 28 is secured in frictional engagement with the rod in a counterbore 27 in the head which is connected by a passage 29 with the reserve chamber. In operation fluid flows through the port 15 on extension of the shock-absorber until the piston covers or passes the port when the increase in pressure opens a spring-pressed disc-valve 33 controlling the piston ports 30. At the same time, a spring-pressed valve 41 at the bottom of the cylinder is opened by suction in the lower part of the cylinder and fluid flows into this part from the reserve chamber through ports 14, 39. On compression of the shock-absorber, fluid escapes through the port 15 until the port is closed by the piston when fluid passes upwardly through ports 29 in the piston controlled by a spring-pressed disc-valve 31 and fluid is also forced into the reserve chamber 13 through ports 40 controlled by a disc-valve 44 at the bottom of the cylinder and through the ports 14. The ports 14 are formed by circumferentially-spaced ribs 17a on a cap 17 fixed to the lower end of the reserve chamber.

Title: Improvements in or relating to solid-state control systems
IPC: F23N5/20
Filed: 1969-03-04
Abstract: 1,263,133. Burner control. HONEYWELL Inc. 4 March, 1969 [23 May, 1968],No. 11549/69. Heading F4T. [Also in Division H3] A condition responsive sensor e.g. a flame detector controls a relay through an amplifier, the relay having at least one pair of contacts controlling a solid state switch which unshunts an impedance in series with the relay coil on operation of the relay to reduce the power dissipation. Power is supplied to a boiler control circuit through a safety switch 14 and a thermostat 13, which when closed energizes a transformer 11. One secondary winding 31 supplies through a full wave rectifier 32 a relay coil 3R in series with a safety heater 35 coupled to a safety switch SS. Operation of relay 3R closes contacts 3R2 energizing a fan motor 20, pressure from which closes an air switch 25 which supplies D.C. to a control system 10 applied to a conventional fuel burner including a fan and motor 20 thus charging a capacitor 64 causing a transistor 51 to conduct and shunt a resistor 52. Another capacitor 58 is charged rendering a unijunction transistor 57 conductive hence energizing a relay coil 1R which is held over its own contacts 1R3, contacts 1R4 energizing a pilot valve 21 and ignition means 22. Another secondary winding 30 supplies a flame responsive circuit 40 the voltage at terminal 43 being relatively high when a flame is sensed by a sensor 24, hence a transistor chain 44, 47 allows current through a relay coil 2R, hence contacts 2R3 energize a main valve 23. Operation of contacts 2R1 removes the potential from resistors 60, 61 allowing capacitor 64 to discharge which renders transistor 51 non- conductive hence unshunting resistor 52 which reduces the current through relay coils 2R, 3R to a holding value. Current through relay coil 1R may also pass through resistor 52.

Title: Improved method of and circuit for producing a voltage of substantially triangular or trapezoidal wave-form
IPC: H03K4/06
Filed: 1949-05-02
Abstract: 672,251. Saw-tooth generating circuits. PHILIPS ELECTRICAL, Ltd. May 2, 1949 [May 5, 1948], No. 11651/49. Class 40 (vi). Triangular or trapezoidal waves having a predetermined repetition frequency are produced by mixing two trains of rectangular waves, the repetition frequency of which differ by the predetermined frequency, and removing unwanted high-frequency components present in the output circuit, the mixing being effected in such a manner that the output depends upon the product of the two waves. Pulse trains 8 and 9 are applied to the first and third grids respectively of a mixer valve 1, the bias voltages being arranged so that the valve only conducts when the pulses overlap. It is explained that the output comprises triangular waves. together with a number of high-frequency components which, when the frequency of the rectangular waves is made sufficiently high, are above the highest desired components of the triangular wave. The undesired components may therefore be removed by an R.C. filter 16. The anode current of the valve is limited by the anode resistor and the output amplitude is accordingly independent of the amplitude of the rectangular waves. If the two rectangular waves are not symmetrical in time, trapezoidal waves are produced.

Title: Method of and apparatus for making plastic precision mouldings  for medical and dental purposes
IPC: A61C13/14
Filed: 1974-03-15
Abstract: 1442041 Injection moulding ETAB DENTAIRE IVOCLAR 15 March 1974 [15 March 1973] 11658/74 Heading B5A In a method of making a precision moulding for medical or dental purposes, a polymerizable plastics material 19 is injected from a store into a mould cavity 23 and polymerized at a rate which decreases towards the injection aperture 8, and additional polymerizable material is injected from the store into the cavity 23 to compensate for shrinkage. Preferably the gradient of the rate of polymerization is achieved by producing a temperature gradient from the remote end of the cavity via the injection aperture 8 to the store, by thermally insulating the source of heat from the surface of the mould near the injection aperture and from the store. Fig. 1 shows apparatus for making a denture, comprising a mould 12, 12<SP>1</SP> made of plaster of Paris, mounted in two half casings 1, 1<SP>1</SP> closed by covers 5, 5<SP>1</SP> of material of low thermal conductivity. Teeth 24 of plastics material may be inserted into the mould cavity prior to injection moulding. The half casings 1, 1<SP>1</SP> have neck parts 2, 2<SP>1</SP>, and recesses to receive two halves 6, 6<SP>1</SP> of an insulating member. An insulative sleeve 9 is inserted in the neck parts 2, 2<SP>1</SP>, being spaced therefrom by an annular air gap 7. The mould parts are clamped together by means of a ram 14 which can be actuated by a screw press or an hydraulic press acting on a spring housing 15 and a set of cup springs 16. The force exerted on the housing 15 can be maintained by rotating a wedge ring 18 with respect to a fixed wedge ring 17 and securing the rings in the adjusted position. Polymerization can be carried out in a heating bath. The moulding material may be housed in a storage container 20 inserted in the sleeve 9. A cup-shaped insert 21 may protect the injection piston from the polymerizable material. This may be a mixture of at least one monomeric and at least one polymeric ester of acrylic acid or methaorylic acid. Modifications.-Instead of using a temperature gradient, the gradient of the rate of polymerization may be produced by increasing the concentration of a catalyst in the material initially injected, or by irradiating the material for polymerization, the radiation being more intense at the part of the mould remote from the injection aperture.

Title: Improvements in or relating to the contacting of finely divided solids with gases
IPC: B01J8/24
Filed: 1950-05-11
Abstract: The entrainment of fines from a fluidized bed of finely divided solids, for example carbonaceous solids undergoing gasification by means of steam and/or oxygen, is reduced by maintaining in the bed a percentage of fines, particularly those having a particle size of less than 40 microns, substantially greater or smaller than the percentage of fines causing maximum entrainment The latter percentage is first determined by experiment and the initial solid feed material is prepared accordingly by grinding and/or screening.  Thereafter the desired proportion of fines is maintained by adding solids of appropriate particle distribution, the added solids being either recycled solid or fresh solid feed material.  In the case of carbonaceous solids undergoing gasification the bed preferably contains 40-60 per cent. of solids having a particle size of less than 40 microns.
